According to the trade association’s midyear “Sales and Forecasts” report, wholesale revenue from such new-tech categories as wearables, connected-home devices, drones, 3D printers and 4K UHD TVs will add about $10 billion to total CE coffers this year.

CEA also lowered its full-year forecast from the 3 percent growth projected in its January report due to “slow economic growth in the first half of the year.”

Breaking out emerging tech, connected-home revenue is expected to grow 32 percent to $967 million; factory sales of drones will grow 52 percent to nearly $105 million, with shipments nearing 700,000 units; and health and fitness products will lead all wearables in unit volume with a projected 21 percent increase, to some 20.3 million devices, spurring an 18 percent increase in wholesale sales, to $1.8 billion.

In 4K UHD, unit factory shipments are projected to hit 4.4 million this year, up a whopping 210 percent, with wholesale revenue more than doubling to $5.3 billion.

“Consumer technology is about constant and continuous innovation and that is what we are seeing in 2015,” said CEA president/CEO, Gary Shapiro. “As the technology industry naturally ebbs and flows, a new class of tech is generating lots of enthusiasm among consumers. Emerging categories such as 4K Ultra HD, smart home, and health and fitness technology are the breakout stars driving the industry onward and upward.”

Meanwhile, the legacy categories of smartphones, tablets, LCD TVs, laptops and desktops remain the industry’s five-largest revenue generators, responsible for more than half (53 percent) of total tech sales with combined revenues of $119 billion.
